In November 1973, the Berkeley, California-based public radio station KPFA sent a young avant garde musician to a local turkey farm. Jim Nollman was just out of college, and, acccording to the Smithsonian, he had heard "that wild male turkeys can gobble on cue -- especially in response to loud or high-pitched sounds." Nollman's goal was to harness this to artistic, or at least aural, ends.

He made two recordings. The first is a solo track of Nollman singing -- accompanied by 300 of the birds -- "Froggy Went A Courtin'." It's kind of an amazing thing.

More than once, Nollman gets the entire rafter of turkeys to cry "Uh-huh" along with the music. When the track was released to vinyl nearly a decade later, Nollman explained the turkey-euphonic process in the liner notes:

I recorded this one sitting in a farmyard surrounded by 300 tom turkeys. The toms respond to pitch and volume. When a certain relative intensity is reached, each turkey emits a single gobble. A large flock can be manipulated to respond in unison, no different than a basketball player getting a crowd to erupt by sinking a crucial basket.

And, listening to "Froggy," it's not hard to hear Nollman's technique. He'll spike his volume on a chorus. He'll fade out quickly on a verse. He'll pause, sometimes abruptly, to let the toms settle down. He confirms that in the liner notes:

The trick to the process is riding the shared musical energy without aggravating the turkeys. I was once attacked by a flock for getting too frenetic. But if the music is subtle, carefully modulated, accenting those gobble sounds with space between them for the turkeys to compose themselves, one can create a shared music, with a turkey chorus answering for hours at a time.

(Emphasis is mine.)

Nollman went on to found Interspecies, a non-profit devoted to human-animal music-making and communication. A lot of his professional work is spent, as you might expect, trying to figure out what the whales are saying.
